- For International Rankings, the tenth best score in each round will be scaled to 100. Others' scores will be adjusted proportionately.
- If online round organizers participate in the offline finals they will automatically get 100 base points.

Is LMI retropedaling with sudoku?

I had a quick look on puzzle types appearing in LMI sudoku competitions since WSC 2017. Where are the experiments you did in 2017? No more hybrids (well, not speaking about hybriding 2 variants, but puzzle hybrid containing sudoku), No more non-sudoku puzzle à la "where is it?"...

It looks like you changed completely your extreme views about sudoku... Any reasons for that?

Is LMI retropedaling with sudoku?

Thanks for your concern for LMI. On a related note, retropedaling can sometimes be good for us.

I had a quick look on puzzle types appearing in LMI sudoku competitions since WSC 2017. Where are the experiments you did in 2017? No more hybrids (well, not speaking about hybriding 2 variants, but puzzle hybrid containing sudoku), No more non-sudoku puzzle à la "where is it?"...

It looks like you changed completely your extreme views about sudoku... Any reasons for that?

These are your personal views and we respect the "extreme" views but not necessarily agree with them. The FACT is that the above puzzles were part of WSC 2017 as Sudoku puzzles. Of the ~227 sudokus in WSC2017, some have been used in later contests and some have not been used (but may be used later) - in LMI contests and non-LMI contests. Nothing more to read into it.

Also, if you have any genuine feedback or concern please do share. I may be wrong, but your post sounds more like a tirade (directed at LMI) without much constructive input coming out of it.

FYI: This thread is about Sudoku Mahabharat. You may read more about it here.

Yes, I've constructive feedback: Thanks for having retropedaled, LMI sudoku competitions are way much better in 2018, 2019 than the WSC 2017 was. Please continue in the same way.

Thanks !

3) Odd Even Bridge: If the circle has an odd digit, the count of odd numbers on a bridge is done based on the number of instances of odd digits on the bridge, not just the number of different digits. If 7 appears twice it ill be counted twice. Same for even numbers in a circle.

International participants and Unofficial participants

International participants and Unofficial participants from India can now take the test - They can take the rounds in any order till 16th December 23:59 IST.

Congratulations to the winners. I am very happy with my performance and this is my personal best rank in ISC.
A wonderful set of puzzles and of great quality. A day well spent, or should I say night for me.
Kudos to all the organizers for making this event go smoothly. It was a very close experience to an offline final.
Kudos to all the Authors for amazing Sudokus and also testers for ensuring the quality and difficulty of the puzzles.
Eagerly waiting for the next weekend.

What a fantastic collection of Sudokus! Kudos to all the authors, test solvers, and others involved in putting this together in spite of all the challenges this year presented.

I thoroughly enjoyed it. Round 1 was a nice warmup, rounds 2 and 3 were typical rounds you'd expect and then rounds 4 and 5 were a nice change of pace for the post lunch session. Very nicely mimicked the offline experience as far as that could be done.

Congrats to Rohan and Aashay!

Personally it is sad that I missed out in the last round again, but no matter, another year another lesson :)

Congratulations to the winners and also to first-timers who managed to spend an entire day solving Sudokus in a competition setting! A huge shout out to the authors - Akash, Rakesh, Priyam, Kumaresan, Nikola, Tawan, Jan and Cedomir and all the test solvers for a fantastic set of Sudokus. I absolutely enjoyed solving all the rounds. Also, heartfelt thanks to the organizers - Rakesh, Priyam, Amit and others who made sure that the competition went smoothly.

Phenomenal organization by Rakesh, Akash, Priyam, Kumaresan, Amit and all the foreign contributors! The sudokus were of very high quality and the whole experience of mimicking an offline finals was a huge success.
I've never liked online championships but this one is an exception.

Congrats to Prasanna and Rishi for the podium and to Aashay, Jayant and Shambo for topping SM. It's a pity there are no playoffs, they are always fun to watch. Let's hope we return to normalcy next year.

My favourite sudokus:

R1: Killer
R2: Unordered Distances
R3: Odd Labyrinth
R4: Perfect Squares
R5: Core

A big thank you to all core organizers Rakesh, Amit, Priyam, Kumaresan and Akash for making this event possible in an otherwise gloomy year. Special congrats for putting out the set without any broken sudokus! Tremendous effort !
Heartfelt thanks to all authors Akash, Cedomir, Jan Novotny, Nikola, Priyam, Kumaresan, Rakesh and Tawan. Sudokus were of a very high quality and were challenging and really enjoyable :) .

A Very big thank you to all the organisers for a wonderfully organized event. Like others have already mentioned it perfectly mimicked the offline event. The sudokus were of great standards and were really fun to solve. I just loved the mean minis, though my score for that round is a silly goof up from my end and not a reflection on quality of the sudokus :D Great job guys and congrats to all the winners :)

Thank you to all the organisers and the authors for organizing such a flawless online event with such amazing sets of sudokus. Thoroughly enjoyed the whole of it.
Congratulations to all the winners.

At least with way too many puzzles for the time limit (for my skill level) I was able to pick the ones I thought I'd be best at. Was ... 'mostly' right, but I did mess a few up. I have to say, the mechanism for distribution, timing, and submission with instant grading is pretty superb!

I thoroughly enjoyed the event. Its first time and havent given five rounds in a stretch till now. Whatever I had solved, it had beautiful solve paths. I loved the Core sudoku in the last round, the way the loops interacted to get the numbers. Its a beautiful construction. solved or attempted maximum 5 or 6 sudokus in any round. So others must also be constructed with interesting logical solve paths. will try others leisurely.

Seeing these many sudokus in all the rounds, with the testing behind and some sudokus might have not been considered, cannot imagine how many would have been constructed and how much coordination was required to handle the event so smoothly. It really shows the backend effort.

Kudos to all the authors and organizers!!

I enjoyed the event immensely. I am sure there was a lot of hard work put in by the organisers and the authors, and this effort is very much appreciated.

This was my first ISC and it was an extremely interesting day. The puzzles were great and the organizing was so smooth without any glitches. Big thanks to the puzzle creators and testers and the whole team of organizers! You deserve a great applause.

how can I give online test or competition?

Puzzles in this championship are of very good quality. Thanks to all the authors and organisers.

Score Table

Scores for each round are now available in the "Results" link.

Will there be some posting of the international/non-qualified-for-prizes scores? I'd enjoy seeing how I stacked up against other non-India folk, and don't actually know my own score, with the instant scoring being unavailable for round 5 (where I did one, but maybe it wasn't the right answer).

LMI thanks all the international authors and test solvers for their valuable contribution to ISC 2020.

Thanks Cedomir Milanovic, Jan Novotny, Nikola Zivanovic, Tawan Sunathvanichkul, Bram De Laat, Branko Ceranic, Deyan Razsadov, Ken Endo, Tiit Vunk, Wang Weifan, Yanzhe Qiu and Yuhei Kusui!

what about overall rankings?

International Results

Final International (unofficial) results are now available.

The Solution Booklet is now available .

Any certificate being given this year?

Best Author 2020

Congratulations to Prasanna Seshadri for being declared the Best Author for SM1 (Standard).

A big thank you to everyone who participated in my round. I am glad you all liked it so much and am honoured :)

Are certificates being given this year?

I would like to play the puzzles, even though the competition has closed. I am receiving a message that the plug-in isn't working and I assume this is why I can't locate the password to open the puzzle booklet. Can the passwords be made available, please, or could someone kindly explain how I can access the puzzles? Many thanks.

khuski - 2020-12-29 9:43 AM

Any certificate being given this year?

Yes, but our priority has been to start the next year's contests because of how late the ISPC was held last year. Getting back on schedule is essential if we are to prepare towards a World Championship under normal schedules again.

Give us a little time.

Thanks.

Any help required?

It's April 2021. What about certificates /prizes for the year 2020?
